Hi folks. Just curious what your thoughts are on adding an isolation transformer before a P3? Would it be overkill? There has been a lot of discussion on this thread (https://www.computeraudiophile.com/forums/topic/29662-discussion-of-ac-mains-isolation-transformers-started-wposts-moved-from-quotlps-1-troubleshootingquot-thread/). Sounds like the key is select a transformer with very low inter-winding capacitance.
Any input would be greatly appreciated.
